Cryptocurrency exchange Gemini co-founders Cameron Winklevoss and Tyler Winklevoss stated in an interview that Bitcoin is a public, auditable blockchain where anyone can see transaction records, and this openness makes it unsuitable for privacy needs. Privacy coin Zcash is used for private transactions and payments, so the two can coexist. They mentioned that ideally, privacy should be built into Bitcoin, but currently, it is a practical model of Bitcoin storage and Zcash transactions. Bitcoin remains important, but the privacy exposure risk of public chains is greater in the face of artificial intelligence.The Winklevoss brothers stated that Zcash complements the missing privacy features of Bitcoin, serving as a privacy-focused Bitcoin, and the privacy value of ZEC has yet to be fully realized. If it reaches 10% of Bitcoin's market value, ZEC could rise fivefold, easily surpassing $5,000. They are optimistic about ZEC's price performance in the next 5 to 10 years, especially as privacy demand increases, and they described Zcash as a financial privacy protection tool in the era of artificial intelligence, an antidote against AI-driven surveillance and tyranny, and a hedge against artificial intelligence or quantum threats in the cryptocurrency space.

IBM's revenue for the third quarter of fiscal year 2026 was 17.1 billion dollars, a year-on-year increase of about 5%. The adjusted earnings per share were 2.95 dollars, both exceeding analysts' expectations. The company raised its full-year software revenue growth guidance to about 7%–8% and increased its full-year free cash flow growth guidance to over 1 billion dollars.Previously delayed software and mainframe deals, due to customer spending shifting towards data center infrastructure, have started to sign contracts. Free cash flow for the first nine months totaled 8 billion dollars, setting a historical record for the same period. IBM's stock price fell 4.95% in after-hours trading, closing at 239.02 dollars.

Tesla's financial report shows that net profit in the third quarter fell from 1.4 billion dollars in the same period last year to 787 million dollars, a decrease of about 44%. Revenue was 28 billion dollars, roughly flat compared to the same period last year. Tesla's free cash flow in the third quarter was a positive 1.53 billion dollars, while market expectations were a negative 4.921 billion dollars.

The core feature of the NU7 upgrade is to reduce the time interval between Zcash blocks from 75 seconds to 25 seconds. This change means that the time required to wait for three transaction confirmations will be shortened from nearly four minutes to about 75 seconds. This upgrade has been running on Zcash's test network and is awaiting final integration into the node software.In addition to improving speed, NU7 will also bring two important adjustments: first, 60% of the fees collected from each block will be removed from circulation, and these tokens will begin to be returned to miners around February 2031. Second, Zcash's original Sprout privacy system will be completely shut down, so all funds still held in that system must be transferred out before the upgrade is activated; otherwise, they will become unusable.

According to Salus monitoring, the attackers of Drift Protocol transferred 4,600 ETH, worth approximately 11.23 million USD, to Tornado Cash in 46 transactions from another long-dormant wallet between 15:00 and 15:19 Beijing time. This wallet had not made any outgoing transactions for about 202 days and still held 20,285.82 ETH at the time of monitoring.Salus stated that another wallet previously tracked had deposited an additional 6,110 ETH into Tornado Cash on top of the previously disclosed 19,600 ETH, bringing the total deposits of that wallet to 25,710 ETH. The two tracked wallets have cumulatively deposited 30,310 ETH into Tornado Cash.

Coinbase self-custody wallet Coinbase Wallet has announced the launch of a loyalty program aimed at users who continuously engage in exchange transactions. Users can receive up to 50% of eligible exchange fees back in USDC each week. Trader levels are divided based on the eligible trading volume over the past 30 days: Explorer for under $5,000; Trencher for $5,000 and above, with a 15% rebate; Pro for $25,000 and above, with a 30% rebate; Legend for $100,000 and above, with a 40% rebate; VIP for $500,000 and above, with a 50% rebate.Rebates are calculated based on the actual exchange fees retained by Coinbase Wallet after discounts, excluding network fees and gas fees. Levels are updated daily, and higher rebate rates apply immediately upon reaching a higher tier; if trading volume decreases, levels can drop by one tier at most per week. Each wallet's trading volume is calculated separately and is not combined across wallets. Eligible rebates accumulate automatically and are paid weekly in USDC, without the need to enter codes or manually claim.New users who register through a friend referral link can receive a first exchange reward of up to $35 USDC on eligible exchanges and enjoy a 10% discount on eligible exchange fees, with related transactions counting towards level progress. Loyalty rebates are calculated after fee discounts. Users who share referral links can earn 25% of the net fees collected by Coinbase Wallet from their friends' eligible exchanges, paid in USDC. VIP users can also directly contact the product team, get early insights into upcoming features, and receive invitations to exclusive events. The program has regional and eligibility restrictions, and terms may be adjusted or terminated.

Cross-chain stablecoin bridge Cashmere announces expansion plans, with the automated liquidity product Goat LP set to open to all users, followed by the launch of the main product Mountain and the token $CSM. Cashmere Bridge currently supports zero-slippage stablecoin transfers across 16 chains, and Goat Street features 6,666 goat NFTs on the Robinhood Chain. The team states that there is currently no official $CSM, and the related arrangements are part of the current plan and may change.Goat LP targets Uniswap v3 and v4 positions on the Robinhood Chain, with positions remaining in users' wallets as Uniswap NFTs. Automatic reinvestment incurs a 10% reinvestment fee, with Gas covered by the project team; automatic adjustment of ranges and automatic exits both incur a 0.15% fee. The official description refers to it as experimental software. The Mountain code has completed testing and will undergo external auditing before going live. Barn is a soulbound NFT with a maximum of 10 slots, and after issuance begins, new $CSM will be distributed every second. Goat NFTs can be permanently bound to receive issuance shares and cannot be sold or withdrawn after binding.The plan is to issue 1,000 founding Barns, with a guaranteed slot price of 0.125 ETH, whitelist at 0.25 ETH, and public auction prices dropping from 1.5 ETH to 0.25 ETH. $CSM will begin trading through the official Uniswap v4 ETH pool, while market making and tokens on Anvil have been canceled and redeployed due to technical issues. The maximum supply is planned at 666 million, with 10% allocated for official pool liquidity, 25% for the team and treasury with designated ownership, and 65% issued as the system operates. The team also plans to airdrop to Barn participants, Goat Street activators, and early users, with wallets that have listed goat NFTs on OpenSea being excluded.

According to monitoring by the blockchain security agency Salus, the Aztec Connect attacker made 30 transactions on October 19, depositing 1,255.8 ETH (approximately 3.01 million USD) into Tornado Cash. The batches consisted of 12 transactions of 100 ETH, 5 transactions of 10 ETH, 5 transactions of 1 ETH, and 8 transactions of 0.1 ETH.On June 14, the attacker exploited a settlement verification vulnerability in the deprecated Aztec Connect contract to steal approximately 2.19 million USD in assets, including 908.987 ETH as well as DAI, wstETH, and Yearn vault tokens. After holding the funds for about four months, the attacker redeemed the vault tokens on October 19, converting the token assets into an additional 346.767 ETH. The balances of the 6 stolen ERC-20 tokens have all been reduced to zero.

The Zakura team, which operates the Zcash network, released a technical article stating that they plan to allocate a unique viewing key for each ZEC exchange completed through NEAR Intents, in order to block future quantum computers from exploiting public refund addresses to piece together user payment histories. NEAR Intents supports cross-chain token exchanges, and when users exchange the privacy coin ZEC for USDC, the service will publish a Zcash address for the user on the NEAR public blockchain, which will be used to return any unused ZEC.The Zcash address contains a public key generated by the wallet's viewing key, which cannot be reverse-engineered by ordinary computers, but large quantum computers running Shor's algorithm could theoretically deduce the key from the address. Zcash wallets can generate multiple seemingly unrelated addresses, but they typically share the same viewing key. Once an attacker cracks it, they can associate all payments received by the account and read the amounts and notes. Zakura's solution allocates a unique viewing key for each exchange, while the spending key remains in the user's main account. Even if the future refund address is compromised, the attacker would only be able to see payments related to that specific exchange.This design also addresses a practical issue: wallets conducting hundreds of exchanges would generate hundreds of keys, requiring each key to scan the entire Zcash chain during backup recovery. Zakura's solution is a privately queryable database that uses private information retrieval technology, so when the wallet inquires about the refund destination, the database will not know the address being queried. Zakura claims that wallets built on its open-source library (including Vizor) will be able to add this feature in the coming weeks, and hardware wallets will follow after firmware support, ahead of the January quantum-resistant payment target set by Zcash developers this month.

Binance launched the Covered Call and Cash-Secured Put strategies on October 15.These two strategies allow users to sell options contracts while holding the required collateral to earn premium income. Users must provide the corresponding collateral, with Covered Call using stocks as collateral and Cash-Secured Put using cash as collateral.

On October 13, 2026, the Bank for International Settlements Innovation Hub released the second phase report of the Aurum project, themed "Exploring Privacy-Enhancing Technologies for Digital Cash." This phase implements a privacy-protecting digital cash prototype based on the existing Aurum codebase, helping policymakers understand how relevant technologies can alleviate the dilemma between privacy and compliance in digital cash.The prototype adopts the principles of privacy by design and default privacy, demonstrating practices that lie between complete anonymity and complete transaction transparency, and achieving customizable features to meet business needs in compliance and operations. The project indicates that privacy can be embedded in the design of digital cash through technology, rather than solely relying on institutional guarantees, thereby reducing unnecessary exposure of personal and transaction data while maintaining compliance and system integrity.Privacy-protecting designs can assist central banks and policymakers in understanding the relevant considerations and trade-offs. The prototype's functionalities demonstrate policy flexibility between privacy, transparency, compliance, and other attributes, which can be calibrated according to different policy choices and risk preferences. In addition to digital cash, central banks can further explore privacy-enhancing technologies in more use cases, with the report listing several usage experiences.

According to monitoring by PeckShield, hackers minted 19 million THEO tokens on the Base chain, then exchanged them for 700.8 ETH (approximately 1.76 million USD), and transferred the ETH to the Ethereum mainnet via a cross-chain bridge.As a result of this incident, the THEO token has fallen by 92% in the past 24 hours.

According to on-chain analyst Ai Yi (@ai_9684xtpa), a large holder who accumulated 5,147 ETH at an average price of $1,886.7 from August 12 to 13, 2026, transferred 5,170 ETH to Tornado Cash for "washing" in batches 5 hours ago, worth approximately $12.82 million.This portion of tokens has an unrealized profit of $3.056 million, and the purpose of the transfer is unknown.

According to monitoring by Lookonchain, SkyAI, which has held over 2 million SOL worth approximately 214 million USD, has recently been selling a large amount of SOL. SkyAI has disclosed that it recently sold 1 million SOL, worth about 107 million USD, and stated that it may continue to sell.On-chain data shows that since October, SkyAI has transferred out 1.57 million SOL, worth approximately 175 million USD. Its average purchase price was around 194 USD, and it currently has an unrealized loss of over 160 million USD.

The blockchain project Tempo released a report indicating that the Financial Accounting Standards Board (FASB) plans to adjust accounting rules for stablecoins, allowing eligible tokens to be classified as cash equivalents on company balance sheets, or reducing accounting barriers for enterprises adopting stablecoins.Under current accounting practices, stablecoins, even if fully backed by U.S. dollars, may not be counted as cash reserves reported by the company, thereby affecting liquidity ratios and loan covenants. The proposed rules allow companies to use stablecoins for payments and settlements but require them to have direct redemption rights with the issuer. Purchasing USDC through exchanges may not necessarily meet the criteria for classification as cash equivalents.In its 2025 annual report, Coinbase classified USDC and other payment-type stablecoins as cash equivalents, based on its redemption arrangement with Circle. The public comment period for the FASB proposed rules will continue until November 19, after which the board will review feedback and determine the final accounting changes and effective date. At the time of this proposal's release, the market size for U.S. dollar stablecoins had exceeded $300 billion.

On-chain detective Specter posted on their personal channel that between October 9 and 10, the attacker addresses related to the CryptoBilis Ledger hardware wallet incident deposited 2990.3 ETH into Tornado Cash, worth approximately 7.45 million USD.Monitoring shows that the attacker previously withdrew funds to 14 addresses, then cross-chained to ZEC via NEAR Intents and processed for privacy. Specter stated that the attacker partially reused previous deposit addresses to submit withdrawal transactions, and some withdrawal transactions were initiated by wallets associated with the addresses that paid Gas fees during the theft, thereby linking the funds to the withdrawal actions.Currently, the attacker continues to transfer and hide the related funds. The previous CryptoBilis incident involved supply chain risks of the Ledger hardware wallet, and Ledger has stated that they are investigating and reminding relevant users to pay attention to device security.

According to The Defiant, on-chain records of the Ethereum blockchain show that a wallet related to the CryptoBilis theft has transferred 464 ETH to the mixing protocol Tornado Cash.On-chain data indicates that these funds first passed through an intermediary address and were then dispersed to four deposit wallets, while the source address currently retains about 700 ETH.

According to Salus monitoring, the attacker of the cryptocurrency payment service provider Triple-A has transferred 4,970 ETH (worth approximately 12.4 million USD) into the mixing tool Tornado Cash.In July of this year, the attacker stole assets from Triple-A's own treasury, with public estimates of the loss being around 11.8 million USD. After bridging the funds across chains to the Ethereum network and completing the token exchange, the attacker dispersed the funds to two intermediary addresses on September 6. The attacker consolidated the two streams of funds through a single wallet and recharged them in batches to Tornado Cash, which included 49 transactions of 100 ETH and 7 transactions of 10 ETH, with some of the funds sourced from previous withdrawals from the mixer.
